Get list/map of subscriptions

[andrexus]

I'm currently utilizing the GetSubscription(id string) method in the subscription client, which allows to retrieve a subscription by its ID. However, I'd like to propose a new feature that could enhance the functionality of the subscription client.

Could your consider adding a new method that returns a list or map of all subscriptions that have been registered by a client?

Use case:
The motivation behind this request is to improve error handling. When an error occurs, the OnError callback is triggered. I want to engage all subscription handlers and pass along the error. As it stands, I need to manually track all subscriptions because the subscription client doesn't reveal the underlying subscriptions map.

This proposed feature could streamline the process and enhance the efficiency of error handling.
